The word 猪肉 is formed by directly combining two meaningful characters: 猪 (zhū), which means "pig", and 肉 (ròu), which means "meat". It is a straightforward, logical compound where the first element identifies the specific animal source, and the second element names the general commodity or substance derived from it. This creates a clear and immediate concept, "pig meat", in the same way one might combine "cow" and "meat" to conceptually form "beef".
